Another 2-person skit you can use on the spur of the moment, if you just so happen to have the props, the main ones being the raincoat and drawings.
Cast: Story teller, Victim, appropriate sound effects & Helpers, raincoat, cup of water
Storyteller: I need a volunteer to take submarine training. (Put victim under the coat and hold up an arm of the coat to use as a periscope.) Now to be a good submarine captain, you must be able to use the periscope. So let's practice a bit. Can you see the fire? How about those tents? The table? The moon? The stars? (Continue until (s)he becomes proficient.) Let's start our mission. You are the captain of this fine submarine, the S.S. Kaput. You are to bring it about on maneuvers and sink enemy ships. So here we go, in the middle of the Atlantic Ocean. Oh! Here comes an enemy ship to the right! Can you see him? (Show a drawing of a ship.) Blow him up! (When he fires, sink the ship.) Good going! Now turn the submarine to port, and then to starboard (Left & right.) Oh, Oh -- there's a storm brewing. (Shake him a bit.) Do you see that Island? Try to go there to seek cover. Can you see the waves? My, aren't they big? And they're crashing against the rocks! What a big storm! Can you see it? Can you see the waves? No? (Pour the water down the arm.)
